I cant sit way back from the monitor.
I can only sit back so far from the desk, and still reach kb/mouse (no, I dont use controllers).
And, my monitor is only 1680x1050.
My work monitors are 1900x1200, and they dont make me sic (of course, I dont game on them either).
No, its mostly the artificial stuff they put into games nowadays, like head and weapon bobbing, dof, and smoothing. I have to turn all that stuff off to even begin to play.
Also, when there are 3 layers (background, foreground, weapon/player), and say only the background, or foreground scales correctly (say background is at 90fov, and foreground is at 70, and weapon/player model is at 60), that messes me up way badly too (I think this is the issue with the serious Sam 2/3 games).
LOTS of people have this issue, its not uncommon at all.
And, I have been gaming since Arcades (70's/80's).
Nowadays, include all that, with an fov that was made for players sitting 10 feet away on a couch (45-65 fov), then port that same game to pc and not touch anything (with the player 1 and a 1/2 feet from the monitor), and you have a lot of users affected.
I am not the only one that is affected by this.
Go to any popular forum (steam, example), and you will find lots of users affected by this.
Fortunately, I am getting used to this game though, and can play for longer periods now (even though I am only at the (3rd? 4th?) bounty guy.
Speaking of which, why am I writing this when I could be playing?
